(Cl. Sue-33) l5 Claims- 1 This invention relates to magazine rifles of the type embodying a sliding breech bolt, and it provides improved means operated by the b-reech bolt for loading the magazine and for controlling delivery of successive groups of cartridges from the magazine to the receiver.

According to this invention, an elongated magazine is xed beneath and disposed longitudinally of the barrel, said magazine opening at its rear end into the receiver and being adapted to contain a plurality of groups of cartridges. Means is provided which is operable by the breech bolt for loading the magazine by forcing successive groups of cartridges into the same from the cartridge receiver. Also, a cartridge lifter is pro.- vided for raising the cartridges in the receiver and thereby successively bringing said cartridges into the path of the breech bolt so that the latter may force the successive cartridges forwardly into the ring chamber. Other means are provided for depressing the cartridge lifter upon rearward movement of the breech bolt after the last one of a group of cartridges has been forced from the receiver into the firing chamber, and for releasing a new group of cartridges in the magazine for delivery into the receiver and onto the follower plate of the lifter.

By employement of this invention, an undesirable laterally projecting or depending magazine is avoided, and the rifle may be operated to successively fire the cartridges of a plurality of groups .which have been previously placed in the receiver and all but one of which has been forced into the magazine by forward movement of the breech bolt.

The exact nature of the present invention, as well as .other objects and features thereof, will become apparent from the following description when considered with the accompanying draw,- Ligs, in which:

Referring in detail to the drawings, Which show an embodiment of the invention applied to a ride having a manually operable sliding breech bolt, A is the barrel having a firing chamber a-, B is the receiver, ,C is the sliding breech bolt, `D is the stock, and E is the forearm.

ln accordance with the present invention, an elongated magazine 5 is iied beneath and disposed longitudinally of .the barrel, and is preferably housed in the forearm, as shown. This magazine .opens at its rear end into the receiver and is adapted to Acon-tain a plurality ,of groups of cartridges, arranged one behind ano-ther and adapted 7to be successively forced into the magazine from the receiver. `A spring catch t, attaci ed toene side of thereceivenhas an inwardly directed free front end l, that normally projects through a side slot 8 at the juncture of the receiver and the magazine into the path of the rearmost group of cartridges within said magazine to releasably hold the groups of cartridges within the latter. A follower or plunger S is slidable in the magazine and is pressed rearwardly by a helical compression spring Eil surrounding a rod Il fixed to and projecting forwardly from the follower. A tube i2, fixed to the front end of the magazine and preferably housed in the forearm, is adapted to guide the rod il and receive it when the follo-wer is forced forwardly by the cartridges as they are loaded into the magazine. Thus, when the catch 6 is flexed outwardly to withdraw its end 'i from the path of the group of cartridges at the rear end of the magazine, such group of cartridges will be forced into the receiver by the follower. v rhe free end of catch E5 extends through a slot i3 in a second resilient catch I4 whose forward end is movable through slot il in front of the end l of catch E. Catch i4 has a reduced outwardly offset shank i5 (Figures 6, 9 and 10) that extents outwardly through a slot It of catch 6. A lever Il is pivoted at one end to catch at I8, and has a cross pin I9 at its free forward end which underlies the shanl: I5 of catch i4. The forward end of a pull bar 26 is pivoted to a lateral arm 2l of lever i?, and the arrangement is such that when the bar 26 is pulled rearwardly the `catch 6 is flexed from the operative position of Figu-re 6 to the inoperative position of Figure l0 so as to allow the plunger Si to force a group of cartridges into the receiver. Also, the catch i4 is tensioned so that its free end will spring into the path of the next group of cartridges in the magazine to hold them in the latter (Figure 10) when the rst group has passed rearwardly to the receiver. Upon release of the bar 2li, the parts return to the position of Figure 6 under the inuence of catch E, the Catch lf2 being retracted so as to allow the second group to be moved rearwardly from the dotted line position of said Figure 6 to the full line position thereof where they are stopped by the catch 6 which has been projected.

A cartridge lifter is provided to successively raise the cartridges in the receiver and bring them into the path of the breech bolt for being forced by the latter into the chamber a upon forward movement of said breech bolt. This lifter consists of a follower plate 22 pivoted to the forward end of a lever 23 which has its rear end pivoted at 24 in the stock D behind the receiver, and which is urged upwardly by a spring 25. Upward movement of lever 23 is limited by a cross pin 26 to a point where the last cartridge in the receiver has been raised into the path of the breech bolt as shown in Figure 7.

Means is provided for depressing the cartridge lifter upon rearward movement of the breech bolt immediately after such cartridge lifter has reached its uppermost position. This means includes a dog 27 pivoted at 26 to Ithe lever 23 and having a short arm connected by a link 29 to one end of spring 25 so that said spring acts to raise the lever 23 and to swing the longer pointed arm of said dog forwardly against the pin 26. lThe breech bolt C has a notch Si? in the under side thereof, and the arrangement is such that the free end of the pointed arm of the dog is spaced below the breech bolt until the cartridge lifter approaches its uppermost position, whereupon the spring 25 raises lever 23 and dog 27 slightly to engage the free end of said pointed arm of the dog in the notch 3ll of the breech bolt upon rearward movement of the latter. Thus, upon continued rearward movement of the breech bolt, the dog 2l will be swung rearwardly and depressed thereby to depress the cartridge lifter from the position of Figure '7 to that of Figure 8. The pull bar 2! is slidably mounted on the stock at one side of the receiver and has a lateral extension 3l at its rear end arranged in the path of the laterally offset free end portion of the pointed arm of dog 2l as shown in Figures 1G and 12. Thus, after the cartridge lifter has been depressed, final rearward movement of the breech bolt causes the dog 2l to engage the extension 3l and pull the bar 2i) rearwardly so as to release the catch and permit the follower S to force a group of cartridges into the receiver and onto the follower plate of the cartridge lifter.

Upon subsequent forward movement of the breech bolt, the spring 25 will swing the dog 2l forwardly away from and below said breench bolt, and upon the next rearward movement of said breech bolt, the cartridge lifter will raise this group of cartridges so that the uppermost one thereof will be disposed in the path of said breech bolt for being forced thereby into chamber -aupon the next forward movement of said breech bolt, as shown in Figure 5. The rest of the cartridges of this group will be similarly fed to the firing chamber by repeating the reciprocation of the breech bolt. Each time the receiver is emptied, a new group of cartridges will be delivered to the same from the magazine as previously described, until the supply of cartridges in the magazine is exhausted. While only three cartridges are shown in each group for the salie of simplicity, it is preferred to construct the rie so that ve cartridges may be provided in each group. Also, the magazine is preferably adapted to receive three groups in addition to one in the receiver. The magazine is arranged so that it does not project in the users way or depend so as to interfere with firing in a prone position, and the rie may be readily adapted to receive the groups of cartridges arranged in clips, if desired. Upward movement of the cartridges the receiver is properly limited by a stop member 32 pivoted at 33 on the stock D at one side of the receiver by means of a spring hinge which normally swings said stop member inwardly to operative position through a slot 35i provided in the frame part 35 in which the breech boit is slidable. The stop member 32 has a thumb piece 36 by which it may be manually retracted to permit insertion of the cartridges into the receiver through the top of the latter when loading the magazine. Stop member 32 has an oblique edge 3l at its rear side so that the breech bolt will cam said stop member out of its path when said breech bolt is moved forwardly.

The rear portion of the breech bolt is provided with a segmental recess 38 and the forward portion thereof has a longitudinal groove 39 which opens at its rear end into the recess 38. A cross pin i6 carried by the breech bolt extends across the forward end of groove 39. A U-shaped cartridge pusher lli is disposed within the stock between spaced members of lever 23, and this pusher is movable longitudinally of the rifle forwardly into and rearwardly out of the receiver. The intermediate portion of the pusher is vertically disposed so that the end portions thereof project rearwardly with the upper end portieri of the same resting on the bottom of frame part 35 and disposed in the groove 35i of the bre-ech bolt when the latter and said pusher are in their rearward positions. At the top and near the front thereof, the pusher is provided with a notch 42 adapted to receive the cross pin lill if the front of the pusher is pressed upwardly when the breech bolt and said pusher are in their rearward positions. Normally, however, the pusher occupies a position with its front end lowered slightly so that the pin l is disengaged from the notch 52. In loading the rifle, the breech bolt is rst moved rearwardly so as to depress the cartridge lifter as previously explained. The front of the pusher l is then pressed upwardly to engage the pin lli) in notch 42 so that when the breech bolt is moved forwardly a short distance, a similar movement is imparted to the pusher and the bottom of the latter rides onto the rear end of the follower plate 22 of the lifter as shown in Figure 1l. The stop member 32 is then swung outwardly and a group of cartridges is placed in the receiver upon the depressed follower plate 22. The breech bolt is then moved forwardly all the way so as to correspondingly move the pusher and cause the latter to push the group of cartridges into :the magazine where they are held by the catch 'EL By limiting the rearward movement of the pusher to the position of Figure 1l, this operation may be repeated until the magazine is iilled. To so limit the rearward movement of the pusher, a stop element 153 is pivoted on the stock at lid, and is urged by a spring Q5 to dispose its front lateral extension d5 behind and in the path of the intermediate portion of the pusher when the latter is shifted forwardly to the position of Figures 11 and 12. been lled, the element 43 may be swung to the position of Figure 10 to permit complete rearward movement of the pusher by the breech bolt until said pusher rides oilc of the plate .22 and slightly lowers at the front to disengage from the pin lill. rihe cartridge lifter is then free to raise the cartridges in the receiver, and the breech bolt may be moved forwardly to push successive cartridges into chamber -awithout moving the pusher el from its rearward position. When the breech bolt is thus moved to its foremost position, the upper end portion of pusher 4| is located in the recess 33 so that the breech bolt may be turned as usual to lock it in such foremost position while a cartridge is being red by conventional firing mechanism, not shown. As shown, the breech bolt has a stud di engageable in front of a shoulder d3 of the frame part 35 when the breech bolt is so turned in its foremost position.

From the foregoing description, the construction, operation and advantages of this invention will be apparent to those skilled in the art.
